An epitome of the Quadripartitum in Plato of Tivoli’s translation (A.2.1) and of Pseudo-Ptolemy’s Liber proiectionis radiorum stellarum (B.18). The text is preceded by a full chapter index of the four books. Book I opens with a detailed account of c. 9 on the fixed stars, followed by chapters 4-8, 10-23 and 2-3 (c. 1 is ignored). The other books present the chapters in regular order.


The only known MS, which may well be the autograph, was copied in northern Italy around the middle of the 14th century, perhaps in Padua between 1338 and 1345 for the text under consideration.
